Integra OBD2 Questions

[Xian]

Shouldn't make any difference other than the CEL illuminating. I used to have a street/DE 2001 ITR with OB2 and a test pipe. Missing the post-cat O2 sensor makes the ECU throw a code but doesn't imapct performance.

there are tricks to fooling the CEL w/O cat

weld in 2nd bung, a ways downstream. Space second bung out off the pipe several inches with a tube so its not reading the exhaust flow very well.

its worked a few times for us.

Good idea... I'd forgotten about that as an option. Looks like spacers are available for cheap:

you can use spark plug " non foulers" too...basically a spacer for spark plugs. We chop em up for 02 sensor bungs in custom exhausts

I was wondering about some way to install the second O2 sensor but make sure it 'sees' what it needs to to be happy. May just run it for a couple events with just the one sensor for now- will see how the project goes.

Thanks for the help!!
